PICKER SPINDLE Filed Dec. 5, 1929 [/VVENTDR 5? aw 0M 5 R/EHARDGTL/RNER tain types-of automatic looms it is customary 4 to employ a. picker spindle or rod alongv which a rawhide picker slides. It is usual Patented Aug. 23, 1932 ,KNOWLES LooM" wonxs, or wononsr nn, nnssnonnsnrrsjn oonronn'rron for massnonusnrrs ricxnn srInnLEi I 'A pp lication filed December- 5, was. Serial No. 411,941.
lhis invention relates to picker spindles 'for looms audit is the general object of the" invention to provide means whereby expansion of the spindle willnot interfere with the proper holding or aligning of the same.
In box looms and .on the plain ends of certo mount thespindle behind the reed line and hold the same securely in-standslor extensions supported by the lay end. Duringthe operation of the loom considerable heat is likely to develop as a result of the fractionalsliding of the picker along the spindle, caus ing the latter to expand. The resultant strain is likely to break or bend the spindle so as to adversely influence the delivery of the shuttle from the box. t is an important object of my present invention to provide telescoping members each of which may be I "feet I provlde a pickerspindle designated tightly clamped to the lay but so arranged that expansion may take place without strain ing either the lay end or the spindle parts.
It is a further object of my present inven-- tion to secure one end of a tubular element to thelay end and slide therein a rod elementhaving one end connected at the opposite end of the lay end, both of these elements being in the spindle.
Vith these and other objects in view whichwill appear as the description proceeds, my
invention residesin the combination and arrangement of parts hereinafter described and set forth in the claims. 7
In the accompanying drawing, wherein a convenient embodiment of my invention is set forth,
Fig. 1 is a top plan view of one end of a lay having my invention applied thereto,
Fig. 2 is a rear elevation of the structureshown in Flg. 1 showing my invention applied thereto, I
Fig. 3 is an enlarged section taken on line 33 of Fig. 1,
Fig. 4 is a vertical section on line 4-4 of Fig. 3; and
Fig. 3.
" Each of the constituent partsof the spindle Fig. 5 is a vertical sectionton line 5 5 of Referringto igs. 1 and 2 Iliave shown .a lay having area-rwall'll and supported by *a sword '12.. 'Box guides-13- receive tongues 14 of a set of shifting boxes 15. A
stand'16 at the outer end of the lay maybe held thereto by means of a bolt 17, whileat theinner end the lay end may be provided with a lug or boss 18. A picker 19 extends through the back wall 11' andhas engagement with the shuttleS, being propelled by the picker stick 20. j a p Except for the form of the stand 16 and lug 18, the matter thus far described is of common construction, the boxes moving vertically between the guides; 13 and the .picker 19 being moved to the right from the position shown in Fig. 1- to :throw the shuttle to the opposite side of the loom.
: In carrylngmy present invention into efgenerally at and comprising an outer tubular element 31 which as shown herein may extend through the stand 16. As shown in Fig. 4isaid stand is split as at 32 andhas extending 'therethrough a clamping screw 33. The latter when screwed tightlyinto position holds the left end of thetubular element firmly in fixed position with respect to the stand 16 and therefore the .lay. I y -Extending through thetubular element is a reinforcing rod 34 secured in the lu g118 in amanner similar to that in whichthe tubular element is held in position. i The lug is split as intothe lower partof the lug, being efl ective to draw theupper portionthereof down into clamping'relation",with respect to the rod.
is adjustable longitudinally in'its ownsupportand the rod 34 is made of such size as" to fit the interior of the tubular element.
a In operation, thepi'cker 19 will slide along the tubular element and the latter will be supin a lineardirection cantake place freely in- 105 .ported atthe outerend by :the stand 16 and asmuch as the right end of said element is spaced a short distance from the stud 18. In
a similar manner any heat which may be communicated to the rod to cause expansion thereof will not result in straining or bowing ofithe rod'or the surrounding tubular element, because of 't'hefact'that the left end of 7 said rod is free. y r a [From the'foregoing .it- Willhefseen .thatl 7' have provided a pair of telescoping elements eachjofwliichhas a 'free end a'n'd each or which has an endsecurely fastenedito the so that expansion of each element-inay take place Without causingibending oinstraining of the spindle.
